Having seen this sort of thing before for art threads, I've decided to throw something together of my own. Unfortunately, I don't have the talent artistically to be able to wow people with my graphical arts, but I do have something else I can offer: my game design skills.

I have extensive experience with D&D 3.5, Pathfinder, and my own in-development 3.5 modification d20 Rebirth. You can review my catalog of d20 system creations here. For systems not listed above (particularly, systems like Legend), I may or may not be able to work with or recommission your work to other designers. If I do so, the rates below may change, but they will not change by much.

Unfortunately, at this time I only have the ability to create things that fit within the OGL or under the terms of the GSL, which means that things like Exalted, Call of Cthulhu, and similar licensed games are not commission-able at this time. This also holds true for proprietary systems like incarnum, shadowcasting, martial disciplines, and invoking. If one of you can happen to get me the hookup with the right people and get me license approval, I will undoubtedly make it worth your while.

4e Class (including 72 total powers, two class feature options, two builds, and five feats):$25

In the event that you require aspects of your commission tinkered with, I will happily do so provided it doesn't require a major overhaul. I determine what is or isn't a "major overhaul". If a major overhaul is required, we'll talk about what that means at that point; at most, it may mean another dollar or two. Generally, I'll do what I can to fit within the bounds of your idea, but I may take liberties in the name of balance.

Be clear about what exactly you want. "A prestige class that turns you into an elemental" has many options open to it. "A five-level prestige class that grants you power over earth and turns you into an earth elemental, doesn't advance spellcasting, and is accessible as early as 7th level" will get you more what you're looking for.

Don't pester me. I'll be completing commissions in the order they're received, with some possible variation by moving quick and/or easy options to the head of the line to get them out of the way first.

If there's a problem with your commission, I'll let you know.

LEGAL DISCLAIMER: Commissions created are released under the OGL or GSL, as applicable. Reproducing my commissions for non-personal use elsewhere requires crediting me as the creator and including the relevant system license. I retain the right to adapt any commission for d20 Rebirth.
